If the information scrolls by too quickly you can use the following command after boot: dmesg | more Quoting one example from the excellent link you cited: The two free disks above (hde and hdg) are the ones we would like to setup as RAID 1 to create /dev/ataraid/d0 raid device. Note that we do not have hdf or hdh because that is how we used the IDE/RAID ports on Promise chip. It is not a good idea to connect two hard disks to the same Promise controller IDE port. In the above example, we used Primary Master and Secondary Master connections on the Promise Technology card. So, more than likely /dev/hdc (or maybe /dev/hda) will be the proper choice for your setup.
